The usage of ASM_FTR_IFCLR(CPU_TR_ARCH_31) requires asm/cputable.h and
asm/feature-fixups.h. Currently these headers are included transitively,
but that transitive inclusion is about to go away.
Hum ...
That was unexpectedly added by commit 9c7bfc2dc21e ("powerpc/64s: Make
POWER10 and later use pause_short in cpu_relax loops")
In theory, vdso/ headers shouldn't include any headers outside of vdso/
I am aware. But this is the dependency as it exists today and I don't really
want to make this series larger than it already is. This is by far not the
only such layering violation in the vDSO headers. I have some patches
prepared...
Explicitly include the headers.

Ack. I'll have to rebase this series after -rc1 in any case. Right now I am
hoping to collect some Acks.
